An amine derivative represented by compound (1) of following Formula 1:
First claim
Opening claim text (preview).
What is claimed is: 1. An amine derivative represented by compound (1) of the following Formula 1: wherein, Ar 1 is unsubstituted group having 6 to 18 carbon atoms forming a ring, Ar 3 is a substituted aryl group, substituted with a triarylsilyl group of 18 to 30 carbon atoms forming a ring or a trialkyl silyl group of 3 to 18 carbon atoms, and L is a direct bond, a substituted or unsubstituted arylene group, or a substituted or unsubstituted heteroarylene group. 2. The amine derivative as claimed in claim 1 , wherein Ar 1 is an unsubstituted phenyl group. 3. The amine derivative as claimed in claim 1 , wherein L is a linker or an arylene group having 6 to 14 carbon atoms. 4. A material for an organic electroluminescence device, the material comprising the amine derivative as claimed in claim 1 . 5. A hole transport material for an organic electroluminescence device, the hole transport material comprising the amine derivative as claimed in claim 1 . 6. An organic electroluminescence device comprising at least an emission layer and a hole transport layer disposed between a negative electrode and a positive electrode, the hole transport layer including the amine derivative as claimed in claim 1 . 7. The amine derivative as claimed in claim 1 , wherein AR 3 is substituted with a substituted or unsubstituted triphenyl silyl, or a substituted or unsubstituted trimethyl silyl.
